Description
.Verbrennungskraftmaschine mit je zwei Kolben in gemeinsamen U-förmigen Zylindern. Die Erfindung .bezieht sich auf VerbrennungskraftTnaschinen, bei denen zwei Arbeitskolben in einem U-förmig gestalteten. Doppelzylinder mit einem gemeinsamen Verbrennungsraum derart zusammenarbeiten, daß durch die Kolben selbst die Einlaß- und die Auslaßschlitze der Kolben gesteuert werden. Ini Gegensatz zu bekannten Vorschlägen greift die Stange des zweiten Kolbens nicht an einem Gelenkzapfen; <ler ersten Kolbenstange an, sondern vielmehr ebenso wie .diese unmittelbar an einem besonderen Kurbelzapfen. Hierdurch wird nicht bloß die bauliche Durchbildung der Maschine verbessert, son@_iern auch die Möglichkeit größerer Freiheit in der Auswahl des Steuerumgsdiagrammes geschaffen..Combustion engine with two pistons each in common U-shaped Cylinders. The invention relates to internal combustion engines in which two working pistons in a U-shaped design. Double cylinder with a common Work together in the combustion chamber in such a way that the pistons themselves open the inlet and the outlet slots of the pistons are controlled. Ini contrary to known proposals does not engage the rod of the second piston on a pivot pin; <l first Piston rod, but rather as well as this directly on a special one Crank pin. This not only improves the structural design of the machine, but also the possibility of greater freedom in the selection of the control environment diagram created.
Durch entsprechende Wahl des Kurbelvzrsetzungswinkels und .der Versetzung der Zylinderachsen gegenüber der Kurbelwelie wird. bewirkt, daß zu Beginn des @erdichtungsliubes entweder die Ein- und A'uslaßschlitze gleichzeitig oder der Einlaßschl:tz nach (1em Auslaßschlitz geschlossen wird.By appropriate choice of the crank offset angle and offset of the cylinder axes opposite the crank shaft. causes that at the beginning of the @erichtungungsliubes either the inlet and outlet slots at the same time or the inlet slot according to (1em Outlet slot is closed.
an kann so erreichen, daß von. Schluß ocs Einlasses an bis zum Beginn der Verdichtung einerseits kein Hubweg verlorengeht, andernteils die Geschwindigkeitshöhe der an.gesavgten Gewichtssäule vorteilhaft in statische Druckhöhe im ZylindLerraum umgesetzt werden kann.an can thus achieve that of. Closing ocs admission until the beginning the compression on the one hand no stroke is lost, on the other hand the speed level the attached weight column advantageously in the static pressure head in the cylinder space can be implemented.
Ein Ausführungsbeispiel ist schematisch in der beigefügten Zeichnung in zwei verschiedenen Kurbelstellungen. dargestellt. In den beiden Schenkeln des U-förmig gebogenen Doppelzylinders z bewegen sich, die beiden Kolben a und, c. Der Kolben a steuert den Auslaßschlitz b, der Kolben o den Einlaßschlitz d.An exemplary embodiment is shown schematically in the accompanying drawing in two different crank positions. shown. In the two legs of the U-shaped double cylinder z move, the two pistons a and, c. The piston a controls the outlet slot b, the piston o controls the inlet slot d.
Bei der Stellung gemäß Abb. i befindet sich der Kolben a unmittelbar vor seiner unteren Totlage und beginnt den Au:slaßsch'litz b freizulegen. Der Körben. c hält den Einlaßschlitz d noch -so lange Zeit geschlossen, bis die Restgase genügend entspannt sind. Nach Überschreiten der unteren Totlage schließt, wie in Abb. 2 gezeichnet, .der Auslaßkolben a. den Auslaßschlitz b zuerst ab, der Einlaßschlitz d bleibt noch kurze Zeit offen.In the position shown in Fig. I, the piston a is immediately in front of its lower dead position and begins to expose the outlet slot b. The baskets. c keeps the inlet slot d closed until the residual gases are sufficient are relaxed. After the bottom dead center is exceeded, as shown in Fig. 2, .the outlet piston a. the outlet slot b first, the inlet slot d still remains open for a short time.
Durch entsprechende Wahl des Voreilwinkels zwischen :dem zum Einlaßkolben c gehörenden Kurbelzapfen f und dem zum Auslaßkolben a gehörenden Zapfen e kann jedes beliebige Maß für das Nachschließen der Einlaßschlitze eingestellt, auch gleichzeitiges Schließen erreicht werden.By appropriate choice of the advance angle between: that to the inlet piston c belonging crank pin f and the pin e belonging to the outlet piston a can any amount set for the closing of the inlet slots, including simultaneous ones Close can be achieved.
Die neue Anordnung besitzt unter anderem den :großen Vorzug, daß sie einfach ist und leicht sehr genau hergestellt werden kann.The new arrangement has, among other things, the great advantage that it is simple and can be easily manufactured very accurately.
